ports of Progress of the Geological Survey of Canada" for 
1875-76 and 1877-78. For many years a number of fossils 
from the Devonian rocks of the Albany river at old Fort Hen- 
ley and of the Moose river, collected by the late Mr. George 
Barnston about 1834 or 1835, have been in the museum of the 
Canadian survey, but nothing appears to have been published 
about them. 
In Keewatin a few fossils, that are probably of Devonian 
age, were collected, in 1886, by Dr. R. Bell at two localities 
on the Attawapishkat river, and by Mr. Low from the Lime- 
stoi^e rapids on the Fawn branch of the Severn river. These 
fossils have not yet been critically studied, but among those 
from the last-mentioned locality there is a recognizable frag- 
ment of Sphcerospongia tesselata, which is one of the most 
characteristic species of the Stringocephalus zone of the Mani- 
toba Devonian. The existence of Devonian rocks on South- 
ampton island has been quite recently inferred from the fact 
that a few fossils from that island, lent to Dr. Bell by a mis- 
sionary in 1898, are similar to those from the Attawapishkat 
river. Dr. Bell had previously stated that the limestone on 
Southampton island is "evidently exactly the same as that of 
Mansfield island."* If this be the case, the limestone of 
Mansfield island may possibly be Devonian rather than Cam- 
bro-Silurian as previously supposed.

The Devonian age of the limestones on Snake island, lake 
Winnipegosis, and Manitoba island, in the lake of that name, 
was asserted by E. Billings, in 1859, ^^ the evidence of a 
few fossils collected therefrom in 1858. At the time Mr. Bil- 
lings was under the impression that these limestones are, as 
he says, "most probably about the age of the Hamilton 
group. "t In 1874 Dr. J. W. Spencer collected some fossils, 
which Mr. Billings pronounced to be also of Devonian age, 
from rocks on the island and shore of Swan lake and on the 
western shore of Dawson bay, lake Winnipegosis. Still
